Event reminder add more than one group

Hello everyone,

so we want to heavily use events and event reminders. Then, we got the event on the website, our members get the reminders and also ppl who register get them.

Thing is, I can choose a role and additionally one group.

But what is, if this needs to be sent to more than one group?

I then could set up multiple reminders and also - I guess - create a dynamical group which contains other groups. But both seems inpractical compared to that smooth select field when I send regular traditional mails, where I can choose multiple groups.
